Abstract (en)
A laundry appliance (12) includes a blower (26) that directs process air (16) along an airflow path (24). A condensing heat exchanger (28) heats the process air (16) to define heated process air (30). A drum receives the heated process air (30) to dry laundry. A pump directs fluid (18) along a fluid path (32). An evaporating heat exchanger (36) cools the fluid (18) to define a cooled fluid (38). A refrigerant circuit (50) directs a refrigerant (52) between the condensing and evaporating heat exchangers (28, 36). A shower area (40) in which the cooled fluid (38) is showered through the heated process air (30) after the heated process air (30) exits the drum to wash particulate matter (28) out of the heated process air (30). The pump directs the fluid (18) towards the evaporating heat exchanger (36) in order to cool the fluid (18), and directs the cooled fluid (38) to the shower area (40).
